Abstract The seawater splitting for green hydrogen production is emerging as a key research focus sustainable energy. Nevertheless, the inherent complexity of seawater, with its diverse ion composition – especially chloride ions, calcium and magnesium ions poses significant challenges in catalyst design. Designing highly active electrocatalysts that can resist corrosion during still challenge. This article presents an overview fundamental mechanisms explores issues encountered at both cathode anode electrode. then shifts to chlorine anode, examining recent advances preventing strategies. Notably, these design strategies, such anionic passivation layers, corrosion‐resistant metal doping, physical barrier situ phase transition‐driven desalination, decoupled splitting, are comprehensively investigated, all which aim enhance catalytic stability splitting. review concludes outlook on practical applications producing through

Abstract Metal–organic frameworks (MOFs) have emerged as promising materials in the realm of electrocatalysis due to their high surface area, tunable porosity, and versatile chemical functionality. However, practical application has been hampered by inherent limitations such low electrical conductivity a limited number active metal sites. Researchers addressed these challenges through various strategies, including enhancing incorporating conductive nanoparticles, modifying structure composition MOFs replacing nodes functionalizing linkers, preparing catalysts thermal processes decarburization conversion into oxides, phosphides (MPs), sulfides (MSs). This review provided comprehensive summary strategies that were employed enhance electroactivity for improved electrocatalytic performance recent years. It also explored future directions potential innovations design synthesis MOF‐based electrocatalysts, offering valuable insights advancing sustainable energy technologies.

It is essential to develop effective and long-lasting electrocatalysts for seawater splitting prevent the unwanted chlorine evolution reaction withstand corrosive nature of in electrolysis technology. In this study, a unique transition metal catalyst developed enhance splitting. The composed ruthenium (Ru) nanocluster anchored onto nickel-iron diselenide nanosheet arrays grown on nickel foam (Ru-MOF NixFe1-xSe2/NF). Ru metal-organic framework-based Ni Fe heterogeneous catalysts exhibit exceptional performance sustaining high-current-density hydrogen reactions (HERs) oxygen (OERs) during electrolysis. Consequently, OER requires minimal overpotentials 250, 290, 310, 390 mV, while HER needs 130, 199, 189, 315 mV attain current densities 100 500 mA cm-2 1.0 M KOH + natural seawater. Moreover, it maintains stability h at steady density or cm-2. Theoretical calculations indicate that including enhances Gibbs free energy adsorption H2O molecules intermediates HER/OER selenide sites. This optimization leads improved electrocatalytic water/seawater context overall water splitting, composite an both anode cathode, needing voltages 1.61, 1.68, 1.71 V obtain alkaline freshwater, simulated seawater, Particularly, retains consistent test period, indicating promising future practical applications.
